` Specification of Letters Patent.

T0 all whom it may concern Be it known that I, ELMER E. HAUER, a citizen of the United States, residing at Springfield, in the county of Clark and State lof Ohio, have invented certain new and useful Improvements in` Rotary Motors, of which the following is a specification, ref 'erence being had therein to the accompanylng drawings.

My invention relates to rotary motors and more particularly to( a motor of this type adapted to drive a tube cleaner and to follow the cleaner in .the tube although it maly be used for other purposes.

he object of my invention is to provide a simple, compact, strong andv efficient motor, easily assembled and readily taken apart for renewal or repairs. It is designed to be driven at a high speed by compressed air or steam although other uid motive `agents mag be employed.' s

further object is to provide improved means for introducing and deliverin the lzonotive agent tothe motor or working c am- With these and other objects in view my invention consists of the `constructions and combinations hereinafterv described and set forth` in the claims.

In the accompanying drawings Figure 1 is a `sectional view of a motor embodying my invention. vFigs. 2, 3 and 4 are crosssections on the lines II-II, III-*III .and 'IV-IV respectively of Fig. 1 Fig. 5 is a longitudinal section on the broken line V-V of Fi 2. Fi s. 6 and 7 are crosssections-On t e lines -VI."and VIL-VII respectively of Fig. 5 and Fig. 8 is .a detail l showing the discharge openings,v at one end of the casing. l l

In the drawings 1 represents a motor cylinder having an outwardly projecting ring 2 forming an abutment. A two-part casing 3 having heads at its outer ends preferably formed integrally therewith, extends over and is screw-threaded to said cylinder with its inner ends tightened against said abutment. Tightening the inner ends of the a strong construction and prevents the casing from jarrin loose.

In t e present instance I have shown the motor cylinder forming a chamber ofsuch dimensions that when the rotary motor member 4 is mounted therein it will conticularly shown in Fig. 2. Piston blades 7 are seated in recesses 8 of the rotary motor member and areadapted to move radially into the chambersn 5 and 6 in a well known manner. The rotary motor member may be mounted upon a shaft; but I preferably form said member with front and rear journals integrally therewith of less diameter than the body thereof as shown. A motor journal bearing member l9 is seated in one part of the casing 3 and a removable bushing 10 is preferably provided to carry the rear journal of the lrotary motor member; and a removable bushing 11 seated in an opening in the head of the other part of said casing is provided to carry the front journal of said rotary motor member. Said front journal portion projects through said head and is screw-threaded at 12 to attach a tube cleaner or other tool to be driven.

Inlet ports 13 extend Vthroingh the rear journal of the rotary motor member into the body of said member and intersect cross ports 14-which open into the working chamlF'atented July 7, 1914i.. lA lpplzlcation led J une 2, 15A-)11. Serial No.630,787.

ber inythe rear of the piston blades. Both the lon itudinal and cross ports may be drilled motor member to the point of intersection. A ported plate 15 seated against the rear end of the mo-tor bearing member 9 is provided with ports 16 adapted to register with the ports 13 of the rotary motor member. Saidy plate is secured by dowel-pins 17.' tO the motor bearing member 9 and said bearing memberv is secured to the cylinder 1 by dOwel-pins 18 so that the ports 16 and 13 will beheld in properrelation to admit the rom the Outer surface of the rotaryy motive agent, said port 16 being made oblong in cross-section and-of reater width at one end than the other, eac of the ports 13 passing the ports 16 from the enlarged to the narrow en A plurality of discharge openings 19 are arranged in a circle throughthe front end of t-he casing 3- and the walls between said openings are beveled or tapered and terminate in sharp receiving' edges 20 as particularly shown in Figs. 7 and 8 so that 'said .discharge openings will receive and discharge the exhaust from the ports 21 in a plate 22 seated ,between said headand the cylinder, in any position to which said head may be turned. f Said plate 22 is secured by dowelpins 23 to the cylinder so as to hold the eX- haust ports inproper relation to the cylinder.

A screw-threaded opening 24 in the rear head of the casing is provided to attach a claim 'having an inlet port v gral rear head with an op .1.

2. In a rotary motor, a motor cylinder, a rotary motor member Withv a rear journal of less diameter than the body thereof and having an inlet port entering through said journal portion, a casing removably secured to said cylinder having an integral head, a removable bearing throughithe open4 end of said casing and means to supply the motive agent to said port. y i
